Description
FIELD OF THE INVENTION
[0001] The present invention relates to burn-in socket, and more
particularly to a burn-in socket in which organizer is provided
such that a flat flexible cable can be securely arranged
therein.
DESCRIPTION OF PRIOR ART
[0002] Central Processing Unit (CPU) and other electrical package,
generally referred to as Package, are undergone a test simulating
its real working environment so as to make sure it functions from
all intended ranges.
[0003] A so-called Burn-In Socket is introduced, and which includes
a floatable housing supported by springs and on which the Package
is seated. The Burn-in Socket further includes a Pusher assembly
pushing the Package toward the housing such that the Package is
electrically contacted with all contacts assembled within the
socket.
[0004] Before an Active Thermal Control (ATC) Assembly is used,
Burn-in Socket along with the Package are set in an oven heated to
a working temperature. Then after a certain period of time or
cycle, the Package is removed for inspection.
[0005] After the ATC is introduced, the followings are achieved. 1)
Each socket is directly heated/cooled; 2) each socket/device
includes an individual temperature monitoring such that a specific
temperature can be maintained/assured by the ATC; and 3)
Cooling/Heating of each socket is controlled through an individual
fans or heater associated to each socket. Accordingly, temperature
uniformity can be controlled within +/-5 degrees Celcius.
[0006] However, one of issues associated with the ATC system is the
wire harness, i.e. cable used to power the heat generating device,
and also signal wire picking up signal from the sensors. Since each
time a socket completes its test, the Burn-in socket is opened to
remove the Package, and then a new Package is disposed for test. If
the wire harness is not well organized, the performance of the ATC
will be compromised, and also once the wire harness is damaged, the
whole Burn-In socket can be blown out.
[0007] Accordingly, there is a need to have the Burn-in Socket
provided with an arrangement such that the wire harness well
organized, and protected, such that the repeated operation of the
Burn-in Socket will not impose any negative effect to the Burn-In
Socket.
SUMMARY OF THE INVENTION
[0008] It is therefore the object of the present invention to
provide a Burn-in Socket, provided with an organizer such that the
wire harness of a heat generating and sensor assembly can be well
organized and protected, therefore will not be damaged.
[0009] In order to achieve the object set forth, an Burn-in Socket
made in accordance with the present invention comprises a housing
assembly with a plurality of contacts arranged therein. Each
contact includes a contact engaging portion extends above a
supporting surface of the housing assembly and located within a
package receiving space. A pusher assembly pivotally assembles to a
first side of the housing assembly and includes a pusher. A heat
generating and sensor assembly is supported on the pusher, and
includes a cable extending away and outward of the pusher. A latch
pivotally assembles on the pusher assembly for securely locking the
pusher assembly to the housing assembly. Wherein an organizer is
arranged on the housing assembly such that the cable is securely
arranged and protected therein.
[0010] According to one aspect of the present invention, the
organizer includes first and second arms extending toward from each
other from an outer wall of the first housing and jointly defining
a slot.
[0011] According to another aspect of the present invention,
wherein the wire harness, which is the FPC, and the flat flexible
cable is securely arranged within the slot defined by the first and
second arms.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
[0019] Referring to FIGS. 1 to 6, particularly to FIG. 1. A burn-in
socket 1 made in accordance with the present invention comprises a
housing assembly 10 including a first housing 11, and second
housing 12 floatably attached to the first housing 11. The second
housing 12 is floatably supported on the first housing 11 by means
of four coil spring 13 or other equivalent. The first housing 11
defines a space 111 to receive the second housing 12. Both of the
first housing 11 and second housing 12 are provided with
passageways in which each is assembled with a contact 14.
[0020] The second housing 12 defines a mating interface or
supporting surface 120, in which a contact engaging portion 141 of
the contact 14 extends beyond the mating interface 120 so as to
electrically engage with an electrical package. The contact 14
further includes a compliant portion 142 which will deform to
accommodate the downward movement of the second housing 12 with
respect to the first housing 11. The second housing 12 has
peripheral wall 121 which defines a package receiving space 122
jointly with the mating interface 120, and properly receives the
package therein.
[0021] A pusher assembly 20 pivotally assembled to a first side 110
of the first housing 11, and includes a pusher 21. The pusher
assembly 20 includes an opening 201 in which the pusher 21 is
snugly assembled therein. The pusher 21 defines also an opening 210
which will in align with the package seated on the second housing
12.
[0022] A heat generating and sensor assembly 30 is securely
supported on the pusher assembly 20. The assembly 30 includes a
heatsink 31 in which at least a heat generating device, and a
sensor are mounted (not shown in Figures). The assembly 30 also
includes a cable 34 providing power to the heat generating device
32, and picking up signal from the sensor 33. The cable 34,
according to a preferred embodiment of the present invention, is a
FPC, flat flexible cable. Of course, other type of cable are also
acceptable, as long as it makes the assembly 30 works according to
its intended purpose.
[0023] A latch 35 is pivotally assembled on the assembly 30 for
securely locking the assembly 30 to the first housing 11. The latch
includes a hook 351 which can be locked to an anchor 112 on the
first housing 11. The latch 35 further includes a tab 352
interlocked to a mount 113 of the first housing 11.
[0024] In order to well keep the FPC 34 organized, an organizer 114
is arranged on the first housing 11 adjacent to the mount 113 of
the first housing 11. The organizer 114 is integrally formed with
the first housing 11, and includes first and second arms 115, 116
extending toward from each other from an outer wall of the first
housing 11 and jointly defining a slot 117. The FPC 34 can inserted
and well organized within the slot 117 defined by the first and
second arms 115, and 116.
[0025] In operation, the latch 35 is firstly unhooked from the
anchor 112 such that the assembly 30 can be tilted to an opened
position, such as shown in FIG. 5. Then, the package to be tested
can be seated onto the mating interface 120 which is accessible
from this tilted position. After the package is well seated, the
assembly 30 is closed, and the latch 35 is locked again to the
anchor 112, and the tab 352 is hooked to the mount 113. And then
the testing cycle can be commenced.
[0026] It can be well noticed that since the cable 34 is well
seated and protected within the organizer 114, the cable 34 will
then be well protected and secured.
[0027] Although the present invention has been described with
reference to particular embodiments, it is not to be construed as
being limited thereto. Various alterations and modifications can be
made to the embodiments without in any way departing from the scope
or spirit of the present invention as defined in the appended
claims.
